We demonstrate an acousto-optic tunable filter based on a two-mode elliptical-core fiber. The filter is operated at 1090 nm as a broadband notch filter used for spectral flattening and as a bandpass filter with subnanometer bandwidth. When used for spectral flattening the FWHM bandwidth is optimized

## Abstract A nonlinear twoโcore fiber coupler with unequal cores (phaseโmismatched) is analyzed by using coupledโmode theory. Based on the solutions of the coupledโmode equations, it is demonstrated that even though there is a difference in core diameter, the unequalโcore fiber coupler (phaseโmism
Nonlinear coupling characteristics taking account of evanescent field overlap were evaluated numerically by assuming a Gaussian field distribution for the mode field in nonlinear directional couplers (NLDC). The nonlinear coefficients Q3 to Qs were found to be Q3 = 3.7 x cm-', Q4 = Qs = 0 for the pl
